keep the mage/range account as it is with HP low and no melee stats, 1 pray. train the range with cannon + range guild etc. to keep HP low. then pk looters with it!!! HP will rise with pking and you could train it normally a bit and it will still be an O P looter/scout killer
For the 31 pray account, keep either keep 1 attack and use it to range -> obby maul, or get 50 attack/99 str and make it a maxed pure. other option would be to make it a 31 pray dharok account.
